ABSTRACT
Objective:To study the immunologic and endocrinologic mechanism of Chinese herbs in the treatment of abortion Methods:SD rats injected with bromocriptine 0 125 mg/d subcutaneously(sc)during day 6~8 of pregnancy were used as aborting model Uteruses of the rats treated with or without Chinese herbs were taken out at day 12 of pregnancy for counting embryoes and determining mRNA levels of Th1/Th2 type cytokines in decidua by semiquantity RT PCR Results:The insufficiency of PRL and P in serum during gestation was related to embryo miscarriage remarkably A predominant Th1 response at the maternal fetal interface is harmful to pregnancy Aborting rate induced by bromocriptine was decreased after treating with Chinese herbs Chinese herbs can increase serum PRL and P , then trigger a predominant Th2 response in the model Conclusion:With it's effect of increasing PRL and P in serum and the Th2 bias response at the maternal fetal interface, Chinese herbs can reverse the abortion effect of bromocriptine
